Imac g3 (tangerine) motherboard diagram

Hi everyone, I bought an imac G3 (tangerine)... does anyone know where I can find a diagram on the motherboard (parts, etc)? And can we use the G3 powermac's processor and RAM card to the imac G3 (tangerine)?

I have a service manual I could attach and email to you. As far as the latter I am pretty certain the answer will be no.

If you could please, also I guess i found out where the processor slot is... turns out, it doesn't have a processor... arghhh. Whatabout a Blueberry G3? Does it have the same processor with iMac G3 trayloading?

I'm pretty sure all the desktops after the G3 Blue Tower had processors on daughter cards. The others used ZIF slots, like the beige G3 desktop and tower. The older iMac's had processor cards, ZIF sockets, and soldered processors if I remember right - depends upon the model. As long and they're both ZIF sockets, you can plug the processors in. The speed of the chip in the G3 Desktops was controlled with a jumper block, a bunch of jumpers like on the back of a hard drive to set master/slave, but in a row- so it was a plastic block that set the speed. I think the iMac's processor speed was set with soldered jumpers, sort of like surface mounted components. Apple lists the Specifications but no manuals;

They did say that the processor should be soldered... but where can I see it or confirm it?

It's on the other side of that big circuit board.

Ok... I'll check the processor at the back of the circuitboard and see if I can find any SGRAM cards here in my location... thanks! Will updated this thread once I don't need any further assistance.... Thanks much ascinto!

It's an SO-DIMM, most likely PC-100, but it'll depend upon the model. Check Apple's spec page;

I looked at that picture again, it looks like you have a Hard drive already connected, and that spare ATA connector is for the CD/DVD, right? And the missing slot is for ram... I'm pretty sure that slot takes two SO-DIMMs, one on top of the other. If you add that ram, you should be able to boot.

When you boot up, you can hold down 'Option' to pick your boot device, 'C' to boot from a CD, and Command-Option-P-R ( and keep holding down for a couple minutes, until you hear three chimes ) to reset the PRAM - Sort of like resetting the BIOS on a PC. If you have trouble booting, you may need to this. If you find a button on the motherboard, sort of like a really tiny metal square with a black button in the middle, or something close to this, push it after you install the ram.

Can you read the model number, or any information about speed, from the serial number sticker on the unit?

Remember- if you have trouble booting try resetting the PRAM - just hold down Command-Option-P & R ( all four at the same time ) and keep holding it until the iMac chimes three time. Good luck!

Thanks again, I was able to find some RAMs from the local MAC-users community here... will update you what happens, yup, i already have an HD and a CD Rom. Thanks thanks thanks again!
